This pull request adds a 'play the US busy tone 3 times'. As the us-busy-tone is only 1 beep, we wanted to be able to be able to hear 3 busy tones before exiting a call. An example of use is setting an IVR exit action to play the busy tone 3 times instead of 1 time before the call hangs up.
* Add a deleted messages option to voicemail.
Messages are only deleted after a certain amount of time instead of immediately.
The queue can be turned off or on with default setting "use_deletion_queue" in the "voicemail" category.
Changed deleted phrase and add a deleted messages count phrase
Added a program to delete messages that are due for deletion. Also small changes to phrases.
